Let's divide 21216178 by 148
Let's see how many times 148 fits into 21216178.

Going ahead to step 1:
If we divide 2 by 148, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 148

Advancing to step 2:
The number 148 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 148

Let's proceed to step 3:
212 divided by 148 is 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 148 from 212, we get 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 148

Step 4:
The number 148 fits into 641 4 times, leaving a remainder of 49.
The next digit of our result is 4. 
Result so far: 14.0
If we take 592 away from 641, we end up with 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 148

Let's proceed to step 5:
The number 148 fits into 496 3 times, leaving a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
If we take 444 away from 496, we end up with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 148

Going ahead to step 6:
If we divide 521 by 148, we get 3 and a remainder of 77.
The next digit of our result is 3. 
Result so far: 1433.0
Subtract 444 from 521 to get 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 148

Let's proceed to step 7:
If we divide 777 by 148, we get 5 and a remainder of 37.
The next digit of our result is 5. 
Result so far: 14335.0
If we take 740 away from 777, we end up with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 148

Let's proceed to step 8:
The number 148 fits into 378 2 times, leaving a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 143352.0
Deduct 296 from 378 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
820 divided by 148 is 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 143352.5
If we subtract 740 from 820, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
800 divided by 148 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 143352.55
If we take 740 away from 800, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 143352.55 and a remainder of 0.06.
